Abstract

The utility model is an atomizer with a plurality of cylinder groups separating the air inlet and the air outlet. The atomizer comprises a first cylinder group and a second cylinder group inside. The first cylinder group comprises a first air inlet opening, and the second cylinder group comprises a second air outlet opening. The first air inlet opening and the second air outlet opening are respectively communicated with the air inlet and the air outlet of the atomizer through a connecting pipe. Since the first air inlet opening and the second air outlet opening are respectively from different cylinder groups, the air inlet and the air outlet of the atomizer are respectively independent and non-communicating structures, so there will be no problem of cross infection, and therefore the user can be more assured in use.

Description

An atomizer that separates the inlet and outlet ports with several cylinder groups

technical field

The utility model relates to an atomizer, in particular to an atomizer which separates air inlet and outlet ports by several cylinder groups. the

Background technique

The host of a general nebulizer has an air inlet or an air outlet to achieve the purpose of suction and spray or atomization respectively, and the nebulizer can also be used for medical activities, such as: ear and nose in general medical institutions For the medical care of patients' nasal cavity and throat in laryngology and nursing institutions, the suction function of the main unit of the nebulizer can be used together with a nasal aspirator to suck the nasal mucus and phlegm in the patient's nasal cavity; The spray function of the nebulizer main body is matched with a sprayer (or nasal irrigator) to clean the nasal cavity, throat or wound, etc.; Spray treatment for nose or throat. the

However, the inside of the housing of the general atomizer includes a cylinder group with an air inlet opening and an air outlet opening and a motor, and the cylinder group is respectively provided with a check valve on the ventilation paths of the air inlet and the air outlet opening, so that The cylinder group has the functions of air intake and air outlet, and each opening is respectively connected with a connecting pipe to communicate with the outside of the atomizer shell, so that the cylinder group has an air intake pipeline and an air outlet pipeline respectively, and makes The outlet ends of the air inlet pipeline and the air outlet pipeline respectively form the air inlet and the air outlet of the atomizer. Under normal conditions, the air inlet pipeline and the air outlet pipeline do not communicate, but due to the The stop valve is usually a bendable soft body, so the air inlet pipeline or the air outlet pipeline can be opened and closed by means of whether the check valve is bent or not. However, after the atomizer is used for a period of time, the Some non-return valves may be incompletely closed when the inlet pipe or the outlet pipe should be closed due to elastic fatigue, so that the inlet pipe and the outlet pipe may form communication, and there is a crossover. The risk of infection, so the inventors think that there is a need for improvement. the
